The CMA-100 has a balanced input impedance of 50K ohm, can withstand being attached to live power lines with voltages up to 250V, and provides up to 115dB of gain.
Additionally, the CMA-100 utilizes a unique AGC that has 105 dB of control.
Signals as large as 31V peak-peak can still be monitored with minimal distortions. Manual gain control can be set to 0, 25, 50, 75, or 100 dB.
Filters can be positioned to FLAT, LOW PASS, HIGH PASS, or BAND PASS.
